Title: Developing method
Inventor: OKAMOTO YOSHIKAZU
IPC: G03G9/113
Filed: 1980-05-14
Abstract: PURPOSE:To prevent the deterioration of image quality due to a change of a carrier with the passage of time by replenishing a toner previously mixed with a carrier in the average ratio between carrier and toner consumed per one copy by development. CONSTITUTION:Magnetic powder is mixed with resin to form a fine magnetic carrier having 10-40mum average particle size, and this carrier is mixed with triboelectrically charging toner particles in 100:(2-20) mixing ratio. The resulting developer is magnetically held on the surface of a developing member set in a developing vessel to develop a latent image on a recording body. At this time, the consumption of the carrier is restricted to <=20%, and a replenishing toner having <=20wt% carrier content is replenished. Thus, a little carrier is consumed, and a little fresh carrier is replenished, so the developer in the developing device is always kept at a constant level.

Title: Weighing machine
Inventor: ABE YUUZOU
IPC: G01G23/37
Filed: 1978-05-24
Abstract: PURPOSE: To make displaying easier to read by fixing the numerical values of the digit of the lowest place of display which will cause fluctuations during rotation of a weighing table owing to its vibrations at the specified value.  
     CONSTITUTION: While a weigting table 1 is still, a switch S 2  is on the terminal a side and the displacement quantity of the magnetic pole piece 8 detected with a magnetic sensor 9 is subjected to A/D conversion 12 through an operation amplifier 11 to generate digit signals D 1  thru D 3  and numerical value signals Q 0  thru Q 3  which are then inputted to a decoder 13. Next, weights are displayed in a display device 15 through a display drive 14. When the weighing table rotates, the switch S 2  shifts to the terminal b side and the digit signal D 3  being the lowermost place digit signal does not input to an OR gate OR 1 , hence the outputs of the AND gates A 0  thru A 3  become zero at this timing and the lowermost place digit display of the display device 15 is fixed at 0. Thus, even if the weighing value of the lowermost place digit changes owing to vibrations, etc. of the weighing table, the display does not change and therefore the easier-to-read display may be obtained.

Title: Rubber check valve
Inventor: NEMOTO HIROSHI
IPC: F16K15/14
Filed: 1991-03-27
Abstract: PURPOSE:To provide a rubber check valve which can flow a large amount of fluid and whose pressure loss is small by providing plural inclination valve parts radially provided with a slit opening/closing function. CONSTITUTION:When fluid such as gas flows from an inlet part, slit opening/ closing parts 21-24 open in a radial form to flow fluid in a single direction. When fluid such as gas flows under an ordinary condition or in an opposite direction to the above, fluid hits inclined parts 29-36, so that the slit opening/ closing parts 21-24 close. Accordingly, a function of flowing fluid only in a single direction but not in the opposite direction is provided. An opening part is relatively large, so it is possible to provide a rubber check valve which can flow a large amount of fluid and whose pressure loss is small. Besides, it is possible to close the valve immediately and accurately with integrated parts 25-28.

IPC: G06F9/48
Filed: 1991-03-28
Abstract: PURPOSE:To prevent the errors of a microprocessor by fetching an accurate vector signal. CONSTITUTION:The interruption generating means 5-7 produces successively the interruption request signals INT3a, INT2b end INT1c in the order of higher preference levels. When at least one of means 5-7 outputs an interruption request signal, an INT signal is outputted to set a microprocessor in an acknowledge cycle state. An interruption level holding means 8 fetches the interruption request signals of higher preference levels with preference based on the priority set previously when plural interruption request signals are inputted at one time. The state of the fetched signal is kept as it is for an 'L' period of the signal. Then only one of interruption signals corresponding to each input signal is set at 'H' and outputted. An interruption vector generating means 9 produces and outputs a vector signal corresponding to the signal of an 'H' state.

Title: Inspecting method for mixed fiber of different contraction
Inventor: ICHIHASHI EIJI
IPC: D02J1/08
Filed: 1979-05-24
Abstract: PURPOSE: To ensure the simple decision for the normal mixing of fibers having different contraction, by spraying the heated gas to the mixed fiber in order to cause the contraction and isolation among the strands.  
     CONSTITUTION: The heated gas is sprayed to part of the mixed fiber having different contraction. Thus the strands contract according to the temperature of the heated gas. And in this case, the difference of length is caused between the strand having a large contraction rate and that having a small contraction rate, and accordingly the strand of a large rate is stretched along with the sag caused to the strand of a small rate each. This sag of the strand is blown away by the heated gas, and thus the isolation is given among the strands of different contraction rate. In this way, the simple decision is secured for the normal mixing of the fibers.
